The Delta Maintainability Model: Measuring Maintainability of Fine-Grained Code Changes

Existing maintainability models are used to identify technical debt of software systems. Targeting entire codebases, such models lack the ability to determine shortcomings of smaller, fine-grained changes. This paper proposes a new maintainability model – the Delta Maintainability Model (DMM) – to measure fine-grained code changes, such as...

Faster Defect Resolution with Higher Technical Quality of Software

We performed an empirical study of the relation between technical quality of software products and the defect resolution performance of their maintainers. In particular, we tested the hypothesis that ratings for source code maintainability, as employed by the SIG quality model, are correlated with ratings for defect resolution speed. This study...
